In habit, size, foliage and fl. strongly resembling Bapistrum ru- 
gosum L., but with the short-beaked pods of Brassica nigrq (L.). 
St. and foliage pubescent dull pale grevish-gr., not smooth and 
shining glaucescent purplish or v. as in B. nigra (L.) and of mostly 
lower growth, 1-2 rarely 3 ft. high. St. and branches hard and very 
tough, the latter remote straggling spreading or declining naked or 
inconspicuously leafy retro-pubescent produced into long racemose 
corymbs and without the peculiar pendulous stalked smooth 1. of B. 
nigra (L.). Fl. pale lemon-y. ; sep. erecto-patent. Pedic. com- 
pressed 4-angular little more than one line long. Pods 3-5 lines 
long (of which the beak is one line), ■§ line broad subquadrangular 
slightly compressed and turgid 3-4 or 5-seeded ; beak short com- 
pressed 2-edged 4-angular ovate or lanceolate, contracted at its base, 
about the length of its pedic. or half that of the pod, 1-2-seeded, 
upper seed fertile, lower abortive. 
This pi. is so entirely local and confined to an extent of not much 
more than half a mile along a coast-road not formed above 8 or 10 
years and 12 or 15 miles from Funchal, that it is extremely unlikely, 
though certainly possible, that it should have been really met with 
by Masson, particularly as no spec, from him is extant in BH., and 
no entry of it as a Mad. pi. has been made by Solander in his Mad. 
List. Notwithstanding, therefore, this recent discovery of the true 
S. incana~L. in Mad., I still think that the pi. intended by Yon Buch 
(p. 196. no. 320) under that name must have been the universal S. 
nigra L. (otherwise entirely omitted) as affirmed at p. 27 of this 
work.
